Can I play it as casual player?

I like oxygen not included but I never develop rocket science because I am causally play for a hour or two. I like to build items randomly and see what happen.

Do you recommend Frostpunk for me?

I read a few review and it seems I must follow specific strategy in order to pass. For a casual player like me will I be stuck in early stage?

I don't ... think it really matters. Just play on Normal or Easy and you can play however you like. Strategies are for more difficult levels.

Default difficulty is "normal" but quite challenging for beginners.
You can play the game on easy if you want a more relaxed experience. Never tried easy difficulty, it must be quite boring...

I mean there ARE difficulty levels, but this game is kind of brutal for city builders. Still a good game though, much better than some.

Short answer: Yes.

Long answer; Also yes, but longer.
Start up an endless game in serenity mode, set the difficulty to whatever you want between Medium and Easy and finally I'd recommend The Flats map because it comes with plenty of room to build into.
While you will still need to learn the odd system on how the game works, for the most part all you will have to do is gather resources and then build stuff with them.
Then just research the Beacon, get some scouts out there and any people shortages you have will go away soon enough.

May I ask a follow up question:
Can I play it again and again start over, while every time the results are different?

For the scenarios, no not really. For endless mode, yes to a limited degree.

If that's the sort of thing you are looking for, Cliff Empire might be a better choice honestly.
